alt Hacker Newsdynamic objects are still largely unsolved problem, I just tried to approach it in this demo. also this particular place doesn't have reflective surfaces, but technology supports it - check for example this splat https://superspl.at/scene/ff1d0393 or this one https://superspl.at/scene/6c822f84
This is better, but I think that a demo with more reflections and radiosity would be much more impressive
